Following up on the smash success of Great Little War Game, Rubicon Development has released an addition: GLWG All Out War. Rubicon is sure to point out that this game is not an official sequel, but instead an additional two campaigns, following up where the first game left off.

The developers also warn that these new levels are "fiendishly challenging," and advise new players to check out the original game first to get a handle on what they're up against.
